精密加工的花岗岩基座板,作为光学镜头定心机的基础结构部件。
精密加工的花岗岩基座板,作为光学镜头定心机的基础结构部件。采用高等级花岗岩制造,具有优异的尺寸稳定性、极小的热膨胀和卓越的振动阻尼特性。为安装光学元件提供几何稳定的基准平面,确保镜头对准和定心操作中的微米级精度。 利用花岗岩固有的高密度、低导热性和优异的振动吸收特性,形成稳定的基准平台。刚性非金属结构最大限度地减少热变形和机械共振,即使在环境波动和操作振动下也能保持光学元件的精确对准。

Granite offers superior vibration damping (3-5 times better than cast iron), minimal thermal expansion (1/3 of steel), and maintains dimensional stability without stress relief aging. It doesn't rust or corrode, and its natural frequency characteristics reduce resonance during high-speed operations.
Through precision grinding and lapping processes using diamond abrasives, followed by laser interferometry verification. The non-porous surface is sealed to prevent moisture absorption, and regular calibration ensures flatness within 5 microns per meter over the operational lifespan.
Minimal maintenance: regular cleaning with isopropyl alcohol, protection from direct impact, and annual flatness verification. Avoid thermal shocks and chemical exposure. The non-metallic surface doesn't require rust prevention treatments.
